I'd like to comment here on your post, Porcilina, and also the one you were responding to:
I think it can be a good approach in discussions with individuals on this topic to stay away from these belief elements. For all the reasons mentioned.
I think it's a little naive to think we can avoid ideologies by prohibiting religion, or things that look like religion. This idea that non-religious philosophies or ideologies are somehow neutral, and fundamentally different that religious ones, is completely false. Everyone has some idea, even if poorly thought out and articulated, about what is real, how things fit together, how to think about truth, what gives things meaning, and so on.
Western society, even in modern secular contexts, still for a long time had a pretty strong basis in a shared set of ideas about these things. Now, perhaps, it's less so. But any set of ideas that schools are going to teach kids about the nature of science, or truth, or justice, or fairness, is coming from a worldview perspective.
Personally, I think kids in a good faith school have a real advantage, because they can learn the underlying beliefs that structure what they are being taught, which allows the possibility of being critical of them, or seeing how they influence their own thought. Most non-religious schools just take a set of widely held ideas about reality for granted, and teach from that as if it's self-evident. But it's not, and if students believe that they can't challenge those ideas.
